Izihlanganisi ze-hose ze-hydraulic zensimbi ezingenasici zizikhonkco eziphambili kwiinkqubo ze-hydraulic, kwaye ukusebenza kwazo kuchaphazela ngokuthe ngqo ukuthembeka kwenkqubo, ukuqina kunye nokhuseleko. Phakathi kwezixhobo ezininzi, intsimbi engenastainless yeyona nto ikhethwayo kwizihlanganisi ze-hydraulic hose ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, ukomelela okuphezulu, kunye nokuqhubekeka kakuhle. Eli nqaku liza kugxininisa kwizinto eziphambili kunye neepropati ze-stainless steel hydraulic hose connectors.
1. IiPropati ezisiSiseko zeNtsimbi eNgatyiwayo
Insimbi engenasici yi-alloy material esekelwe kwintsimbi kunye nokongezwa kwezinto ezixubileyo ezifana ne-chromium (Cr), i-nickel (Ni), kunye ne-molybdenum (Mo). Olona phawu lwayo luphawulekayo kukunganyangeki komhlwa. Oku kungenxa yefilimu ekhuselekileyo ye-chromium oxide (i-Cr₂O₃) eyenziwe kwindawo yentsimbi nge-chromium, ekhusela ngokufanelekileyo i-oksijini kunye nomswakama ekuhlaseleni ngakumbi isiseko sesinyithi. Intsimbi engatyiwayo ikwanika ukomelela okuphezulu,-ukuxhathisa ubushushu obuphezulu, ukuxhathisa impembelelo, kunye nokuqhubekeka okugqwesileyo, iyenza ilungele iinkqubo zoxinzelelo oluphezulu, ukungcangcazela okuphezulu, kunye neemeko zokusebenza ezirhabaxa.
2. Iindidi eziqhelekileyo zeeMpahla zeNtsimbi
Ekwenzeni i-hydraulic hose connectors, iintlobo ezahlukeneyo zensimbi engenasici, ngenxa yokubunjwa kwazo ezahlukeneyo kunye neempawu, zifanelekile kwiindawo ezahlukeneyo zokusebenza. Oku kulandelayo zizinto eziqhelekileyo zentsimbi engenastainless:
(1) 304 intsimbi engenastainless (18-8 intsimbi estainless)
I-304 insimbi engenasici iyona nto isetyenziswa ngokuqhelekileyo i-austenitic stainless steel, kunye nokwakheka kweekhemikhali kubandakanya i-18% ye-chromium kunye ne-8% ye-nickel (kungoko ikwabizwa ngokuba yi-18-8 stainless steel). Esi sixhobo sinokumelana ne-corrosion efanelekileyo, ukuqina kunye ne-weldability, kwaye ifanelekile kwiinkqubo ze-hydraulic jikelele, ngakumbi kwiindawo ezingenayo imidiya eyingozi kakhulu. Nangona kunjalo, i-304 insimbi engenastainless inokungena kwi-pitting corrosion kwiindawo ezine-chloride ion (njengamanzi olwandle okanye izisombululo ezithile zeekhemikhali), ngoko ke kufuneka isetyenziswe ngononophelo phantsi kweemeko eziyingozi kakhulu.
(2) 316 intsimbi engatyiwayo (intsimbi yodidi lwaselwandle)
I-316 insimbi engenasici yongeza i-2 - i-3% ye-molybdenum (Mo) kwi-304, ephucula kakhulu ukuchasana kwayo kwi-pitting kunye ne-crevice corrosion, ngakumbi kwiindawo ezine-chloride ion. Ngoko ke, i-316 insimbi engenasici ihlala isetyenziselwa ubunjineli baselwandle, izixhobo zekhemikhali kunye neenkqubo ezinobungozi kakhulu ze-hydraulic. Umxholo wayo ophezulu we-nickel uphinda ukhulise ukuqina kobushushu obuphantsi kwaye ufanelekile kuluhlu olubanzi lobushushu.
(3) 2205 duplex steel stainless
I-2205 duplex steel stainless steel yi austenitic -ferritic duplex steel stainless equlathe malunga ne 22% chromium, 5% nickel kunye ne 3% molybdenum. Ibonakaliswa ngamandla amakhulu, ukumelana nokugqwesa okugqwesileyo kunye nokumelana kakuhle noxinzelelo lwe-corrosion cracking. Xa kuthelekiswa nentsimbi yesiko e-austenitic stainless steel, i-2205 duplex stainless steel iqhuba ngcono kuxinzelelo oluphezulu{8}}, oluphezulu{9}}olunxitywayo lwe-hydraulic systems kwaye ilungele i-oyile, irhasi kunye nemimandla yemizi-mveliso enzima.
(4) 317L kunye 310S intsimbi engatyiwa (special corrosion{3}}resistant applications)
Kwimeko-bume ezonakalisa ngokugqithisileyo, ezifana ne-asidi eyomeleleyo,{0}}ubushushu obuphezulu be-oxidation okanye i-sulphur{1}}equlathe imidiya, iintsimbi ezingenastainless ezine-alloy contents eziphezulu, ezifana ne-317L (umxholo ophezulu we-molybdenum) kunye ne-310S (i-chromium ephezulu, umxholo we-nickel ephezulu), ingakhethwa. Nangona ezi mathiriyeli zibiza kakhulu, zinokubonelela ngobomi obude benkonzo kwiimeko zokusebenza eziyingozi kakhulu.
3. Iikhrayitheriya zokuKhetha izinto zeNsimbi eStainless
Xa ukhetha imathiriyeli yentsimbi engenastainless hydraulic hose fittings, qwalasela ezi zinto zilandelayo:
Imithombo yeendaba esebenzayo: Enje ngeoyile yehydraulic, amanzi, kunye nezisombululo zemichiza. Imidiya eyahlukeneyo ineempembelelo ezonakalisayo ezahlukahlukeneyo kwintsimbi engenasici.
Indawo ekusetyenzwa kuyo: Okufana nobushushu obuphezulu, uxinzelelo oluphezulu, ukungcangcazela okuphezulu, okanye ukuba sesichengeni sangaphandle (umz., iindawo zaselwandle).
Iimfuno zokusebenza koomatshini: Njengamandla okuqina, ubomi bokudinwa, kunye nokumelana nefuthe.
Iindleko:-Iintsimbi zealloyi eziphakamileyo (ezifana ne-316 kunye ne-2205) zibiza kakhulu kodwa zinika ukuxhathisa okungaphezulu kokuhlwa kunye nobomi benkonzo.
Intsimbi engenastainless hydraulic hose fittings zenziwe ngokuyintloko ngeentsimbi ezingenasici ezifana ne-304, 316, kunye ne-2205. Isixhobo ngasinye sihambelana neemeko zokusebenza ezahlukeneyo ngenxa yokwakheka kwe-alloy ekhethekileyo. 304 insimbi engenasici ifanelekile kwiindawo zoshishino ngokubanzi, i-316 insimbi engenasici ifaneleka ngakumbi kwi-marine00, i-stainless2 ifaneleka kakhulu kwi-stainless2 kunye ne-2. iindawo ezinzima ezinoxinzelelo oluphezulu kunye nokunxiba okuphezulu. Ukukhetha izinto ezifanelekileyo zensimbi engenasici kunokuphucula kakhulu ukuthembeka, ukhuseleko, kunye nobomi benkonzo yenkqubo yakho ye-hydraulic, ngaloo ndlela kuncitshiswe iindleko zokulondolozwa kunye nokuphucula ukusebenza kakuhle ngokupheleleyo.
